2. Design and function
2.1 Description
The model FLM-CAI (with guide tube Ø 6 mm) and model FLM-TAI (with guide tube
Ø 12 mm) high-accuracy level transmitters are used for the continuous measurement
of the level of liquid media in vessels. The measurement procedure used exploits the
physical effect of magnetostriction and is largely independent of the temperature. It is used,
especially, where very precise level measurements are required, such as in the chemical
industry.
In these operating instructions, the FLM is described with cable connection on the side of
the probe head. As cable connection, an M12 cable gland (also with M16 adapter), an M12
connector or an M20 or ½ NPT female thread are possible. As a further variant, there is
an FLM with an M12 connector on the probe head cover. Model BLM-TAI can be used for
mounting to bypass chambers.
